Abstract

The invention discloses a single-focus phase-controlled focusing ultrasonic transmission device which comprises a transmitting pedestal, a plurality of transmitting oscillating elements, a plurality of power ultrasonic power sources and a computer. The transmitting oscillating elements are mounted on the transmitting pedestal. Each transmitting oscillating element is connected with one end of each power ultrasonic power source. The other ends of the plurality of power ultrasonic power sources are independently connected with the computer. The transmitting pedestal is provided with planar ladder-shaped inclined planes. Each transmitting oscillating element is mounted on one inclined plane of the transmitting pedestal, and the adjacent transmitting oscillating elements are positioned on different inclined planes of the transmitting pedestal, so that the perpendicular bisector of the transmitting surfaces of all the transmitting oscillating elements are crossed at a focus. The ultrasonic transmission device further comprises a phase differential generator. The other ends of all the power ultrasonic power sources are independently connected with the phase differential generator. The phase differential generator is further connected with the computer. The ultrasonic transmission device has the advantages of ring-shaped interface transmission, reduced power source number and phase control function.

Description

technical field [0001] The invention relates to an ultrasonic emitting device, in particular to a single-focus phase-controlled focusing ultrasonic emitting device. Background technique [0002] The transmitting base of the existing ultrasonic transmitting device usually adopts a concave surface, and the transmitting vibration elements are installed in the concave surface. In order to make all the transmitting vibration elements focus on one point, the processing accuracy of the concave surface of the transmitting base is very high. In the ultrasonic transmitting device During the production process, the yield rate of the concave launch base is low. And this ultrasonic emitting device cannot perform phase control. Contents of the invention [0003] The purpose of the present invention is to solve the disadvantages of low yield and incapable phase control of the concave spherical emitting base in the prior art, and provide a single-focus phase-controlled focusing ultrasoni...
